Should I Continue Based on My Fake Door Test Results?

I conducted a Fake Door Test to gauge user purchase intent before building an MVP. Here are the test results:

Landing page visitors: 470 Users who took purchase action: 3 Users who signed up for the waitlist: 2 Given these metrics, should I continue pursuing this idea?

The conversion rate is lower than I expected, so I'm unsure whether to stop or move forward, considering that at least three users showed purchase intent.

Can you help me decide the next step?
